Another of the legs of the coupling 14, indicated at 20, is directedrearwardly and is disposed at right angles with respect to the leg 19.The pipe is secured to the support 9 by flanged straps 21, and holdfastdevices 22. Each strapis ofcircular formfor the purpose of'surroundingthe pipe 10. See'Figure 7.

See Figure7. Connected to the legs 17 of the couplings 12 and 16 and tothe leg 19 of the coupling 14 are rearwardly directedsprayingelementswhich communicate with the pipe 10 for the reception of thespraying solution therefrom and as'each of the spraying elements is ofthe same construction, but one will be described, as the description ofone will apply to the other.

Each spraying elementcomprises a pipe 2 1 of substantial length havingits rear portion formedwith a downwardly inclined returned bend 25.Attached to the free end of the returned bend isa nozzle 26 of theadjustable type to control the spray, as for very small I 1ams the sizeof the spray should be cut down and increased for larger plants. Thepipe 24 has its' forward end peripherally threaded, as at 27 forconnection with a rearwardly directed'leg of a coupling. Con-;

nected to the'vertical leg 19 of the coupling ltis' an upstandingslightly flexible feed pipe 28-for conducting the solution from the tank2.to the pipe 10.- ,The-feedpipe 28 is connected with the tank 2, as at29, and communicatingwith the connection29 is an air pump 3'.

ments project beyond 'and are arranged below the nozzles 26.

Adjustably secured to the part 31 of each of the supporting elements isa series of flexible planttilting'members 35 and each tilting memberisof a length to extend from one 1 outer' to'the other outer supportingelementi eral tilting members are secured to. the supporting elements at37, 38, 39 and 40. The tilting members are provided for the purpose oftilting the plants 41 downwardly in a forward direction. 1

The supporting elements are positioned over the furrows and the majorportions of the spraying elements are positioned over the plants, whileremaining portion of each spraying element, which is the return benddepends below the'tops of the plants.

Owing to the construction and arrangement of the spraying device, inaccordance with thisinvention, as the vehicle moves forwardly the plantswill be tilted and the nozzles will provide for the spraying'of thesolution forwardly towards the underside'of the plant, and also upon theplant growth under the leaves and under such conditions the plants arethoroughly sprayed. The nozzles of the spraying elements are arranged asubstantial distance below the forward tilting member 36. The tiltingmembers are so disposed that the rear tilting member will be positioned"below the nozzle, the tilting member arranged forwardly of the reartilting member will be positioned-abovethe latter, and the forwardtilting member 35 willbe positioned above the adjacent rear tiltingmember. Although the spraying device is shown as set up with threetilting, members 35, yetit is to be understood that this number can beincreased or dimi-n ished if desired. The tilting member 36.;is

arranged a substantial distance above the for ward tilting member 35andtilts the plant in a manner so that the 'support 9 can clear theplants without damage thereto.

The tilting members maybe loosened or V tightened depending on theheight of the plant. YVhen employing the device on very small cotton thesupport 9 will be lowered to the desired extent to provide forsatisfactorily spraying the plant. 1 This can also be controlled @to acertain extent byloosening or tightening/up the tilting members. The

spray itself may be raised or lowered by turn ing the pipe 10about threequarters of an inch. By turning the pipe 10 rearwardly the entire systemof spray pipes would be raised and by turning it forwardly the systemlowered. I t

It is thought the many advantages of a spraying device, inaccord'ance'with this invention, can be readily understood, and althoughthe preferred embodiment of the in no Y vention is as illustrated anddescribed, yet it parts of the supporting elements and aris to beunderstood that changes in the details ranged forwardly of said supplypipe. of construction can be had which fall within In testimony whereof,I aflix my signature the scope of the invention as claimed. hereto. his
